Specification oi' Letters Patent.

Patented Aug. 15, T905.

Application filed November 2,1903. Serial No. 179,572.

To (/,ZZ 1071/071@ it '1n/ty concern:

Be it known that l', ERNs'r Nonne, a subject oit the King' oi Prussia, German Emperor, and a resident ot' Weissentels-on-the-Saalc, in the Province of Saxony, German Empire, have invented certain new and useful Improvements in Chains, of which the following' is an exact specification.

My invention relates to improvements in chains, and more especially to the construetion of chain-links consisting' ot' a wire the ends of which are bent inward so as to form a closed loop.

According to my invention the extremities of the wire ends are bent so as to form a hool; and catch and grip one above the other or embrace each other. Thereby the durability of the link and resistance against tension and traction is considerably increased.

ln order to make my invention more clear, l refer to the accompanying,` drawings, in which- Figures l and 2 are different side views of part of a chain constructed accordingl to my invention. Fig. 3 is a section on line AB ot' Fig. l. Figs. It and 5 are side views of a modified construction. Fig. 6 is a section on line C D of Eig. 4.

Tn the construction shown in Figs. l to 3, c is a wire bent so as to form a chain-link. The ends and c of the wire are bent toward the inside oiE the link so as to form a loop ot' a circular or similar torni. The extremity ol the end c is bent horizontally, and the extremity of the end b is bent somewhat downward,so that the extremities catch one another, hereby obtaining' a chain-link which oijlers ,great resistance against beingl deformed.

lin the modiiication shown in Figs. t to 6 the extremities ot' the ends 7) and c are twisted one around the other, as may be seen from the section Fig'. 6. This construction has the advantage that the ends and ff cannot be so easily .removed one from the other in the crossdirection.

Having' thus 'fully described the nature ot' my invention, what T desire to secure by 'Letters Patent ot' the United States isY A chain-link consisting' ot' a wire, the ends ot' which are bent inward so as to i'orm a closed loop, the extremities of the ends beingI twisted around each other and bent so as te form hooks which catch one another, substantially as described and for the purpose set iorth.

Tn testimony whereof l have signed my name to this specilication in the presence ot' two subscribing witnesses.

ERNST NOLLE.
